Sanatorium Concrete Roughness

Generated from: Seamless tileable greyscale roughness map, 1024x1024, plain greyscale tones only, no colour, no lighting, no shadows, no text, no watermark. Surface: weathered poured concrete wall of an abandoned hospital. Mid grey base value around 200 for dry rough concrete, darker values around 90 for damp wet patches and vertical water streaks, slightly lighter values around 220 for polished worn areas. Soft cloudy blotchy variation, fine grain noise, faint vertical streaks. Flat orthographic view filling the frame. Edges match exactly on all four sides for seamless tiling. Technical game PBR roughness map.
